Vanessa was conducting an experiment on hair growth. She had her test subjects take vitamins for several months and then measured the rate the hair grew to compare to her test subjects whom did not take vitamins. Identify the independent and dependent variable in this experiment.

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.

An electron in an x-ray machine is accelerated through a potential difference of 1.00 × 104 v before it hits the target. what is the kinetic energy of the electron in electron volts?

How is an electron dot structure used to represent a covalent bond?
